At this, at control circuit 200, except input, have the input voltage of the making operation based on turn signal switch WS and danger warning lamp switch HS, while on circuit, having produced leakage current, also input has the voltage based on this leakage current.This leakage current such as the turn signal switch WS due in being exposed to external environment condition or danger warning lamp switch HS enter rain etc., input side contact 212,216 and 210,214 conductings of outlet side contact and produce.SW input circuit 226 has the voltage based on leakage current is cut off in this circuit, only detect the input voltage of the making operation based on turn signal switch WS and danger warning lamp switch HS, downstream the function of the CPU238 of side output specified signal (magnitude of voltage).
The input of holding circuit 228 is connected with CPU238 and battery 202, and output is connected with 5V adjuster 230.This holding circuit 228 has turn signal lamp LF, the LR based on judging at CPU238, the danger alarm lamp action of RF, RR keeps the function of the connection status of this CPU238 and battery 202.That is, when danger alarm lamp moves, from CPU238 to holding circuit, 228 inputs have connection signal, and during input has this connection signal, holding circuit 228 makes this CPU238 and battery 202 in connection status.
Lighting Control Assembly 11 possesses this holding circuit 228, even thereby, at the opening operation (driving of engine 22 stops) that carries out when danger alarm lamp moves carrying out ignition switch IS, also in order to carry out this danger alarm lamp action, utilize holding circuit 228 from battery 202 to CPU238 power supply source voltage until danger warning lamp switch (HS) is carried out to opening operation.Thus, can maintain the danger alarm lamp action that the driving based on CPU238 is controlled.Therefore, when stopping, also improving by engine 22 highlighting of vehicle.
On the other hand, danger warning lamp switch HS is being carried out to opening operation, when the danger alarm lamp action stops, holding circuit 228 is cut off the connection status of battery 202 and CPU238, stops the supply line voltage to CPU238.In this case, if again ignition switch IS is not carried out to making operation, cut off from battery 202 to the CPU238 supply line voltage, therefore, even for example after engine 22 stops, turn signal switch WS, danger warning lamp switch HS are carried out to making operation, also can prevent that turn signal lamp LF, LR, RF, RR from lighting (flicker).Therefore, for example, in the situation that the third party carries out making operation to danger warning lamp switch HS, can avoid carrying out the danger alarm lamp action.
The input of 5V adjuster 230 is connected with the output of ignition switch IS and holding circuit 228, and output is connected with CPU238.This 5V adjuster 230 has the supply voltage step-down from battery 202, stably the magnitude of voltage to CPU238 supply driving use is the function of 5V.
Constant-current circuit 232 has the function of supplying with the magnitude of current of regulation with respect to turn signal lamp LF, LR, RF, RR, with this turn signal lamp LF, LR, RF, RR, arranges accordingly four.The input of each constant-current circuit 232 is connected with CPU238 and battery 202, and LF-LED, LR-LED, RF-LED and the RR-LED of output and current detection circuit 234 and turn signal lamp LF, LR, RF, RR are connected.
Four constant-current circuits 232 are accepted respectively the turn signal lamp flash signal S sent here from CPU238 l, S r, S h, make battery 202 with LF-LED, LR-LED, RF-LED and RR-LED in connection status, from battery 202 to this LF-LED, LR-LED, RF-LED and RR-LED supply with the electric current of regulation and make it luminous.
It should be noted that, only turn signal lamp LF, the RF of present embodiment usingd the aforementioned illumination of less light quantity of carrying out as clearance lamps in motion like that.Therefore, constant-current circuit 232 has the other circuit of the constant current of using from battery 202 supply clearance lamps.
The input of current detection circuit 234 is connected with constant-current circuit 232, and output is connected with CPU238, thereby can be fed back the action of constant-current circuit 232.That is, in the situation that constant-current circuit 232 and LF-LED, LR-LED, RF-LED and RR-LED broken string, even accept turn signal lamp flash signal S from CPU238 l, S r, S h, yet can not flow electric current is arranged in constant-current circuit 232, therefore, by utilizing current detection circuit 234, detect current value, can confirm the broken string state of Lighting Control Assembly 11.Current detection circuit 234 arranges respectively with respect to four constant-current circuits 232, thereby can confirm the broken string state of each constant-current circuit 232, can improve the precision of burn out detection.
In addition, indicator driver 236 has the function that the LED204,206 of turn signal lamp indicator 106 and right turn signal lamp indicator 116 left supplies with the magnitude of current of regulation, with this LED204,206, is provided with accordingly two.The input of indicator driver 236 is connected with CPU238, and output is connected with the LED204,206 of left direction signal lamp indicator 106 and right turn signal lamp indicator 116, is accepting turn signal lamp flash signal S from CPU238 l, S r, S hthe time, supply with the electric current of regulation and make it luminous to LED204,206.
On the other hand, CPU238 possesses I/O Interface and carries out known microprocessor (microcomputer) of calculation process etc. in inside such as applying.In this case, CPU238 also can and be located at the ECU (Engine Control Unit: not shown) of the driving control of carrying out engine 22.
The on/off operation of CPU238 judgement turn signal switch WS and danger warning lamp switch HS and the LED204 based on this judged result control LF-LED, LR-LED, RF-LED and RR-LED, left direction signal lamp indicator 106 and right turn signal lamp indicator 116,206 driving (luminous).At the pre-stored determining program (not shown) that is useful on the on/off operation of judgement turn signal switch WS and danger warning lamp switch HS of this CPU238, implement the judgement handling process of regulation based on this program.
In addition, CPU238 possesses the register (not shown) more than at least three bits that lighting of turn signal lamp LF, LR, RF, RR managed by each action.Turn signal lamp action (action of left direction signal lamp and the action of right turn signal lamp) and the danger alarm lamp action separately of the left and right of turn signal lamp LF, LR, RF, RR controlled by the sign (left direction signal lamp action sign, right turn signal lamp action sign and danger alarm lamp action sign) that erects specified registers.
CPU238 for example is masked as 1 (True) in the situation that be judged as the action of left direction signal lamp via the judgement handling process, makes the turn signal lamp flash signal S of turn signal lamp LF, the LR flicker in left side to constant-current circuit 232 outputs l, in the situation that the action of right turn signal lamp is masked as 1, output makes the turn signal lamp flash signal S of turn signal lamp LF, the LR flicker on right side r.In addition, CPU238 for example in the situation that be judged as danger alarm lamp action via the judgement handling process be masked as 1, output makes the turn signal lamp flash signal S of turn signal lamp LF, LR, RF, RR flicker h.
In this case, turn signal lamp flash signal S l, S r, S hbe with the specified period pulse signal of on-off repeatedly, the left direction signal lamp action based on utilizing the judgement of judgement handling process, the action of right turn signal lamp and danger alarm lamp action are carried to the constant-current circuit 232 of regulation.Constant-current circuit 232 is at turn signal lamp flash signal S l, S r, S hduring connection, make battery 202 and LF-LED, LR-LED, RF-LED and RR-LED in connection status.That is, in the moment of regulation, to LF-LED, LR-LED, RF-LED and RR-LED, supply with electric current, make thus turn signal lamp LF, LR, RF, the RR flicker of expectation.The CPU238 that present embodiment relates to is glimmered by the sign that erects respectively the action of left direction signal lamp, the action of right turn signal lamp and danger alarm lamp action, therefore, for example can change the flicker of left direction signal lamp action (or the action of right turn signal lamp) and danger alarm lamp action constantly, can make turn signal lamp LF, LR, RF, RR carry out the flicker that the free degree is higher.
The turn signal lamp 10 that present embodiment relates to is configured to the above basically, then, the action effect of this turn signal lamp 10 is described.
The motor bike 12 that present embodiment relates to is using the turn signal lamp of left and right 10 as clearance lamps (auxiliary lamp) and thrown light on less light quantity in motion, on the other hand, when the driver is operated being positioned near turn signal switch WS handle 38, based on this operation, make the turn signal lamp 10 of a side with larger light quantity flicker.In addition, when danger warning lamp switch HS is carried out to making operation, make the turn signal lamp 10 of left and right simultaneously with larger light quantity flicker.
Therefore, supply with luminous quantity, the luminous moment of the illumination action based on above-mentioned to the LED124 of turn signal lamp 10 by wire harness 130 from the control part (not shown) of electrical system.As shown in Figure 6, LED124, when being supplied to the electric power of regulation, is the light LL of radial outgoing expansion from front according to its characteristics of luminescence.The light LL of LED124 outgoing enters in protuberance 164 from the notch part 170 of interior lens 128, utilizes the forwards direction guiding of outer shape of protuberance 164.Therefore, protuberance 164 preferably is bent to form as can be from the shape of the forwards total reflection of light LL of LED124 outgoing.Thus, can be by the easily inwardly front surface of lens 128 guiding of the light LL of LED124 outgoing.While having seen through the lens cutting portion 162 of lens 128 front surfaces in the light LL arrival in protuberance 164, utilize the lens face of this lens cutting portion 162 to spread to overall width direction (left and right directions).Therefore, interior lens 128 can penetrate a plurality of light that advance to the oblique the place ahead of overall width direction from the front surface of lens cutting portion 162.The light advanced to this oblique the place ahead of overall width direction enters the outside lens cutting portion 122b of outer lens 122, thus further direction diffusion up and down.Thus, turn signal lamp 10 can irradiate from the front surface of outer lens 122 light of the LED124 spread to overall width direction and above-below direction.
At this, to the wire harness 130 of LED124 supply capability, from protection ring 150, by segment space 172, with substrate 126, be connected.This segment space 172 forms than the tabular of protuberance 164 thin-walleds and forms wider space by eaves section 166, can easily configure wire harness 130.
In addition, wire harness 130 is disposed at this segment space 172, thereby is difficult to see from the outside of turn signal lamp 10.That is, the eaves section 166 that is positioned at the place ahead of segment space 172 has lens cutting portion 162 at front surface, therefore, can make for example, towards the light LH1 in the place ahead (light that, light is reflected by wire harness 130), to the overall width direction, to spread from wire harness 130.Therefore, even see eaves section 166 from the place ahead, because the light LH1 from wire harness 130 is separated into the light that almost can not judge, therefore, can prevent from seeing wire harness 130.In addition, turn signal lamp 10 utilizes the outside lens cutting portion 122b of outer lens 122 to make the also direction diffusion up and down of light LH1 from wire harness 130, therefore, can further prevent from seeing wire harness 130.
In addition, from the oblique the place ahead in the overall width direction of wire harness 130 outside, dispose protuberance 164 towards side, therefore, for the observability in the oblique outside of the overall width direction of particularly easily seeing with respect to subtend car, pedestrian, can more be difficult to see wire harness 130.That is, from wire harness 130, towards the light LH2 in oblique the place ahead, due to the curved shape of protuberance 164, a part of light is reflected, advances in protuberance 164 under the state reduced in light quantity.And the light LH2 from this wire harness 130 towards oblique the place ahead directly arrives lens cutting portion 162 and, to the diffusion of overall width direction, therefore, can further prevent from seeing from the oblique the place ahead in the overall width direction outside.
As mentioned above, the turn signal lamp 10 related to for present embodiment, can be difficult to see the wire harness 130 extended in segment space 172 by interior lens 128.Thus, even cover wire harness 130 such as other members such as not utilizing body cover 74, also can hide wire harness 130.Therefore, when turn signal lamp 10 irradiates, the light-emitting area of this turn signal lamp 10 can be fully guaranteed, thus, better light can be realized.In addition, can wire harness 130 be connected with substrate 126 in the position close to LED124, therefore, can realize the miniaturization of substrate 126, make turn signal lamp 10 miniaturizations.
At this, turn signal lamp 10 also can be set in the coupling part of substrate 126 and wire harness 130 in top view and the overlapping position of protuberance 164.Thus, the coupling part that can utilize protuberance 164 to hide substrate 126 and wire harness 130 when top view, can be difficult to see from outside wire harness 130 more.
In addition, as shown in Figure 6, in the situation that the imaginary line Li that supposition is extended along the overall width direction with the deposited part of interior lens 128 by base component 120, base portion 161 sides of interior lens 128 are disposed at than the position of the outer lens 122 of imaginary line Li, and the top side of protuberance 164 is disposed at the position by substrate 126 than imaginary line Li.That is, protuberance 164 is more outstanding, in the situation that see turn signal lamp 10 from the oblique outside of overall width direction, more is difficult to see wire harness 130.
In addition, integrally formed by the eaves section 166 by interior lens 128 and protuberance 164, need to outside interior lens 128, as other parts, not prepare eaves section 166, can reduce number of components.Thus, the assembling of turn signal lamp 10 is easy, and can reduce manufacturing cost.
It should be noted that, the invention is not restricted to above-mentioned embodiment, certainly can not break away from main idea of the present invention and adopt various structures or operation.For example, interior lens 128 can be located at lens cutting portion 162 structure of front surface for present embodiment so yet, and at the back side (back) of interior lens 128, lens cutting portion 162 are set.
